How to configure Heroku to receive webhooks from GitHub?

Question

I am trying to create a GitHub Webhook that pings a URL whenever one of my repos is updated. I want to ping my application running on Heroku , but I am not sure how to setup Heroku to accept an external webhook.

I see that Heroku can create webhooks, but I don't see if Heroku can receive a payload from a webhook.

Is this possible?

EDIT: I should add, the idea would be when Heroku receives a response from the webhook, a command from the Heroku Scheduler add-on would run. So I guess the real question is if it's possible to have Heroku receive a webhook response and then run a Heroku Scheduler add-on command.
